POINTE A LA HACHE, La. -- On a bright spring day last week at the Pointe a la Hache harbor, Pablo Cervantes was working on his boat. There wasn't a whole lot else to do. Thanks to the aftermath of the Deepwater Horizon explosion and spill in the Gulf of Mexico last April 20, the oyster population that Cervantes relies upon is now decimated. The fate of the oyster beds -- who was to blame and how they will be restored -- is a complicated one that is just one illustration of how the process of quantifying the damage to the Gulf is ongoing and nowhere near over.
